    Applications / Construction
    Technical Characteristics
    Standard Hardware
    Technical Data

    The regulation of the rpm and rotary momentum of direct current motors represent the main focus of application. These appliances can moreover, also be used universally in industrial processes for control and regulation of direct voltage or direct current.

    The unit was designed jointly with experienced plant manufacturers in line with the latest know-how in the field of power-electronics. They are suitable due to their modular concept for the construction of simple variable-speed drives on the designing of expensive multi-motor-drive systems.

    Construction of the appliances

    GISIDIG units are built with fully controlled thyristor-bridges for 2- or 4-quadrant operation. The circuit thyristors are insulated and mounted on a common cooling body.

    The electronic components are structured on two levels at a swivel carriage above the circuit thyristors and are connected to each other with flat band cables. This construction makes it possible for all components to be freely accessible.

    On the level of the thyristor module there are protective circuit breakers, the thyristor control and optionally the field regulation device.

    The basic version can be offered with various optional Hardware-Extension Modules such as for example Technology regulators or communication components etc.

    The machines are fitted in the standard version with an EPROM in which a regulatory structure is stored which can be made operational through simple parametering.

    Technical Characteristics
    • High processing speed and short reaction times through the latest processor technology
    • Fast process communication via Peer to Peer RS232, RS485 and optionally via a PROFIBUS component
    • Solving various complex technological tasks through freely programmable Technology Modules
    • Short time for setting into operation through computerised parametering and monitoring (GISIVIS)
    • Monitoring functions such as for example On-Off switching sequence and indication of faults are included in the standard software
    • Compact metal housing with swivelling device, which enables a problem-free access to all boards as well as the thyristor power components
    • Automatic setting
      Automatic optimisation course for regulator and pre-controls, automatic offset alignment, Trace-Accumulator
  • Simple operation and observing
    Simple parametering of the appliances by means of a 3-key-manipulation and 5 Seven-segment-displays on the basic electronics. As an option it is possible to install an equipment operating field with 2x15-digit LCD display.
    • High Operating Safety
      Safety cut-off switch without engaging the micro-processor (E-stop-function)
    • Standard typ series from 20...850 A, types for 2- or 4-quadrant operation and for 400 V AC or 500 V AC main voltage. Higher currents and voltages via parallel switching of thyristor sets and control with control unit (form R construction). Optional regulated B2H secondary field supply with filed nominal emission depending on equipment type in the range of  DC 1...28 A.
    Standard Hardware
    • Four analog Selector inputs, of which two are sum-and difference amplifier inputs. Wiring of the signals to every relevant point of the control
    • Four analog selection outputs. Every test value can be wired to these outputs
    • Eight digital inputs, of which 6 are election inputs (dial-inputs). Over 60 functions can be actuated selectively
    • Four digital selection outputs. Over 30 positions can be registered as desired
    • Three possible actual value-sources:
      • analog tachometer,
      • all accessible impulse transmitters,
      • measured EMK (for operation without tachometer)
    • Synchronising voltage direct from power part
    • Connection possibility for various hardware expansion components available as optional
      The units can be used via serial interfaces as peripherals of the SPS
    Communication with superior automation systems:
  • A RS 232-interface to the PC-coupling allows direct parameter read-out on the printer or storing on floppy disk
  • A RS 485-Interface for communication with an automation system or direct coupling for digital nominal value cascades (Peer-to-Peer communication)
  • The unse of an interface  component makes connection with the PROFIBUS
  • Controller Software
    With all GISIDIG rectifier controllers an efficient 16-bit-microprocessor takes over all functions of the drive control, drive steering and of communication.

    The units have in the Standard design a series of the technological functions such as for eample superimposed technology regulator for draft regulation, motor potentiometer, digital nominal value cascade, free multiplier, free divider etc. High-dynamic current regulator through blocking period anticipatory control (for more extensive technolgical functions an additional technological component can be used).
    Interactive setting into operation with support of GISIVIS software
  • Menue-guided setting
  • Upload/Download of parameter sets
  • Guided parametering of the analog and binary inputs and outputs
  • Guided adjustment of all control and regulatory functions (technology regulator, motor poti, uptake transmitter, rpm regulator, current nominal value formation, current regulator, EMK-regulator, field current regulator, free function-blocks)
  • Guided parametering of additional components
  • Operating screens for advance control commands and nominal values
  • Trace-booster-graphics, control of outlining, read-outs and graphic representation of the built-in TRACE-buffer built into the GISIDIG.
  • Options

  • Operating panel
    Machine operating field parameters and their contents are displayed simultaneously in clear text and physical detail. Moreover the user can read-off two parametered values (e.g. rpm and anchor current). The operating panel can be installed either in the machine top cover or in the door of an enclosure . The clear text display is available in several languages. Unit with built-in operating panel as option
  • Connection cable for terminal blocks
    The unit terminal block can be integrated with the mounting set in the cabinet terminal strip.
  • Interface converter RS232/ 485
    It converts the RS 232-point-to-point interface into a RS 485.
  • Technology module
    The technology module provides additional complex regulatory functions. The user works with pre-set or freely programmable SW-packages (e.g. for synchronous speed regulation).
  • PROFIBUS-modules
    They serve for open communication vide PROFIBUS or SINEC L2 DP
  • Fully digitalised field regulation
